A new HIGH severity vulnerability was found in Kubernetes in which users may be able to create a container with subpath volume mounts to access files & directories outside of the volume, including on the host filesystem. The issue is affecting the Kubelet component of Kubernetes (Kubelet is the primary "node agent" that runs on each node. It registers the node with the apiserver and launches PODs on it).

Network segmentation is almost as old as computer networking. The evolution of network segmentation went through switches to routers and firewalls, and as modern networks evolved, the ability to better control traffic by operating system native functionality evolved as well. Native controls like IP Tables became lingua franca, alongside access control lists, process isolations, and more. Native controls are not a new concept.

HIPAA compliance law, the Health Insurance Portability and Accountability Act in long form, is one of the compliance standards the public and private healthcare companies need to address for building and maintaining public trust in telemedicine. During the COVID-19 pandemic, telemedicine has been the solution to withstand the excess influx to hospitals and health centers, avoiding unnecessary exposure of patients.

Amazon EKS Anywhere is a new deployment option for Amazon Elastic Kubernetes Service that lets you create and operate Kubernetes clusters on-premises. With it, you can run containerized workloads in whatever location best serves your business. Carefully considering what’s needed for security will help you reduce risk and safeguard against potential threats.

While Kubernetes offers a self-healing deployment platform, there is a fair chance a developer will run into issues that require deeper analysis and debugging to identify configuration problems. Kubernetes supports a loosely coupled, distributed architecture by allowing an application to be broken down into smaller, granular modules—each of which can be written and managed independently.

In this blog, you will learn how monitoring data from your Kubernetes environments can be used to detect indicators of a compromise in Kubernetes. Securing Kubernetes is challenging: Configuration flexibility, large clusters, ephemeral containers, and an ever-growing services ecosystem produce complex environments that open up your attack surface. Adversaries get an advantage because complexity is a natural enemy of security.

It has been a while since I have been excited to write about encrypted tunnels. It might be the sheer pain of troubleshooting old technologies, or countless hours of falling down the rabbit hole of a project’s source code, that always motivated me to pursue a better alternative (without much luck). However, I believe luck is finally on my side.

Today, Sysdig has completed the acquisition of Apolicy to enable our customers to secure their infrastructure as code. I am very pleased to see the Apolicy team become part of the Sysdig family, bringing rich security DNA to our company.

The Sysdig Security Research team has identified a Cryptominer attack hitting a Kubernetes pod running WordPress, related to the recent Botnet Sysrv-Hello. The goals of the attack were to control the pod, mine cryptocurrency, and replicate itself from the compromised system. In particular, the attackers targeted a misconfigured WordPress to perform initial access.
